Describe the bug
In certain cases, a user may have a group ID that cannot be mapped to a name. This is for example the case if the user is in an AFS process authentication group (PAG). The PAG is identified by a random (?) group id. All processes with this GID are in the same PAG. This GID has no mapping to a name.
In this case id -G -n returns with an error respectively getgrgid(groups[i]) (in envmodules.c) returns a NULL pointer.
To Reproduce
Create a modulefile printgroups with the following content:
#%Module
set s [module-info usergroups]
puts stderr $s
Start a shell with a GID which cannot be mapped to a name and try to load the modulefile:
sudo setpriv --ruid $USER --groups 1234567 bash
# Re-initialise Modules (with PREFIX = prefix of Modules installation)
source $PREFIX/init/bash
module load ./printgroups
The error will be something like:
$ module ./printgroupinfo
Loading ./printgroupinfo
Module ERROR: couldn't find name for group id "1234567": no such file or directory
while executing
"module-info usergroups"
(file "/opt/modules/modulefiles/printgroupinfo" line 3)
Please contact <root@localhost
Expected behavior
Either ignore this GID or print it as number.
